Hello Jay,

I did that too not too long ago, have an UV filter on plus the CP ontop of
that. I was using the Nikkor 18-105mm lens. In my photos, the corners where
almost black and couldn't figure out why. So I took off the UV filter and that
problem went away. If I remember right, it only happen on the short end of the
focus.. 18mm but after I took off the UV and only used the CP filter, I didn't
have that problem anymore.

get out tomorrow and take some foliage pictures. I'm using a Tamron 18-200
macro/zoom and have a UV filter on the front for protection only. What problems
would I encounter if I stack my Circular Polarizer on the UV filter or would I
be better to remove the UV filter?
